3.表达 从表达方面来看，发言者的语速较快，导致一些词汇发音不准确。建议发言者放慢语速，注意发音的准确性。此外，发言者在回答中出现了一些不必要的停顿，建议在练习时注意连贯性和流利度。

4.话题发展 Regarding topic development, the speaker's response does touch on the concept of relict behavior and provides an example with the pronghorn and lion. However, the response could be better organized and more coherent. The speaker should begin by clearly defining relict behavior, then move on to explain the example of the pronghorn and lion, and finally connect the example back to the concept of relict behavior. Additionally, it would be helpful to use more accurate vocabulary (e.g., "pronghorn" instead of "prey hole") and ensure that all relevant details from both the reading and listening passages are included in the response.

Original Answer: next behavior Relict behavior(纠正为正确的词汇) refers to the animal's behavior which not does not(使用完整的否定形式) serves for its original purpose for example the prey hole pronghorn(纠正为正确的词汇) which lives in the grasses in the middle north of united states they have the ability to run very fast which can't be caught by any predator nowadays but however because there's used to be lions living in this area so the prey hole pronghorn(纠正为正确的词汇) developed the ability to run in a such faster speed although the lion was disappeared in this area the prey hole pronghorn(纠正为正确的词汇) still have this behavior that's called the relaxed behavior relict behavior(纠正为正确的词汇).

Revised Answer (140 words):

Relict behavior refers to an animal's behavior that no longer serves its original purpose. For example, the pronghorn, which lives in the grasslands of North America, has the ability to run at incredibly fast speeds, making it impossible for any present-day predator to catch it. This speed was once essential for their survival when lions lived in the same area, as they were fast predators that preyed on pronghorns. However, lions have been extinct in North America for thousands of years, and the pronghorn's current predators, such as bobcats and coyotes, are not nearly as fast. Despite the absence of lions, pronghorns still possess this remarkable speed, which is now considered a relict behavior since it no longer serves its original purpose of evading lions.

Original Answer: Relic behaviors are behaviors that show no clear purpose now, but may have original purpose that has disappeared long ago. Relict behaviors are behaviors that no longer serve a clear purpose, but may have had an original purpose that has since disappeared. (将“relic”改为“relict”，使句子更自然流畅。同时调整句子结构，使其更清晰。) The professor uses one example to illustrate this. The professor provides an example to illustrate this concept. (用“provides”替换“uses”，使句子更自然。) There is an animal called American pronghorn, which lives in an open grassland. They run super fast, and too fast that no predator can even catch up with them. And the reason that they run so fast is that a long time ago, the living condition on this plant was different. A long time ago, the lion was the main predator on the plant, and it was critical for the American pronghorn to run fast to escape from the lion. And the lion were like swift-moving animals, and faster than any other predator today. So although lions are extinct long ago, the pronghorn still exhibit this behavior.

Revised Answer (140 words):

Relict behaviors are behaviors that no longer serve a clear purpose, but may have had an original purpose that has since disappeared. The professor provides an example to illustrate this concept: the American pronghorn. This animal lives in open grasslands and is known for its incredible speed, which is so fast that no current predators can catch up with it. The reason for their speed lies in their past environment, where lions were the main predators. It was crucial for pronghorns to run fast to escape from these swift-moving lions, which were faster than any other predator today. Although lions have been extinct for a long time, pronghorns still exhibit this relict behavior, demonstrating how certain behaviors can persist even after their original purpose has vanished.

23. 3.Delivery

The speaker's delivery is generally clear, but there are some instances where the pace could be more consistent. Additionally, there are occasional pauses that disrupt the flow of speech. To improve, the speaker should practice maintaining a steady pace and reducing unnecessary pauses.

4.Topic Development The speaker provides a coherent and well-organized response, explaining the concept of relict behavior using the example of the pronghorn and lion. However, there is room for improvement in providing more detailed support or examples to further clarify the concept. To enhance topic development, the speaker should consider elaborating on how the pronghorn's speed is a relict behavior that no longer serves its original purpose due to the extinction of lions in North America.

5.Language Use

The professor illustrates the concept of relict behavior using the example of a Progonpronghorn(corrected spelling). Firstly, he talks about Progonpronghorn(corrected spelling) which is a deer-like animals which lives in the open grassy plains. One characteristic of this Progonpronghorn(corrected spelling) is that they are super fast, probably the fastest animal onin(more appropriate preposition) that part of the hemisphere, and none of its current day predators can even match up its speed. Now the professor explains why Progonspronghorns(corrected spelling) developed(consistent verb tense) these characteristics. Tens and thousands of years ago, lions usually lived on grassy plains. Lions, unlike other predators, are very shiftswift(corrected word) animals and they were the main predators of this particular Progonpronghorn(corrected spelling). So to escape from the hunting of such lions, it was essential that Progonspronghorns(corrected spelling) developed(consistent verb tense) such pace to traverse the grassy plains and escape from the lions.

The professor illustrates the concept of relict behavior using the example of a pronghorn. Firstly, he talks about pronghorns, which are deer-like animals that live in the open grassy plains. One characteristic of pronghorns is their exceptional speed, making them the fastest animals in that part of the hemisphere. None of their current predators can match their speed. The professor explains that pronghorns developed this speed because tens of thousands of years ago, lions lived on the grassy plains. Lions, unlike other predators, are swift animals and were the main predators of pronghorns. To escape from lion predation, it was essential for pronghorns to develop such speed to traverse the grassy plains and evade these predators. This example demonstrates how the pronghorn's speed is a relict behavior that no longer serves its original purpose due to the extinction of lions in North America.
